If I could give advice to an ancient historian, I would tell Aristotle to test out all of his logical ideas. I knew that back then, he was known for being smart, and nobody questioned his thinkings, But no one ever tested it out. The same thing happened to Ptolemy. He was a very logical, or rational philosopher. He said that because humans were on the earth, the earth was the center of the universe. He was wrong of course. If these people tested their theories out, it would have made a big difference in the Scientific Revolution. During the Scientific Revolution, many people such as Galileo, were sent to trial because the church believed wrong theories. In Isaac Newton's time, he tested out his theories so many times they were known as laws. In that time, he wasn't charged for heresy either.
